”Därför är det viktigt att ta bort en fästing.” : Förkunskaper och behov av information som förutsätts hos modelläsare i två versioner av en webbtext om fästingbett.

Sammanfattning: This study analyzes the semiotic resources in two versions of Vårdguiden's web text about tick bites: one longer version and one in easy Swedish. The aim is to identify and compare the prior knowledge and information need of each versions' model reader. This study is theoretically grounded in social semiotics and health literacy. The method consists of three multimodal text analyzes with ideational, interpersonal and textual sub-analyses.  Both versions presupposing several actual, practical and mental prior knowledge of the model reader. The information need of the versions' model reader is both common and separate. Both versions also presupposing that the model reader needs informing, explanatory, instructive and reassuring messages with a multimodal and multi-sequential presentation. The longer version presupposes more comprehensive prior knowledge and larger information needs. The version in easy Swedish though presupposes some prior knowledge which is not assumed in the longer version. For example, it is prior knowledge of how a tick bite looks like and the prior knowledges which is required when photographic close-ups should be interpreted. The version in easy Swedish also and presupposes larger needs for explanations and instructions. The results hinting what the versions presuppose of the empirical reader and prompting a discussion about how the versions high demands for health literacy can impede the reader friendliness. However, the results show that the versions' design creates possibilities for broad groups to assimilate the content. The study highlights some important challenges which are relevant when texts should be adapted to broad groups.
